phallic-like mass to the north
What would the NYC Subway system look like if it was placed in Seattle? This site made a map and thought it would look something like this:

This map is to scale and it’s funny how well it fits. It also makes me realise how dense NYC is, because the entire system doesn’t even reach as far as SeaTac and Redmond. Looking at just the island of Manhattan, the phallic-like mass to the north, you can see it only stretches between Kenmore and the downtown waterfront while remaining too thin to reach Capital Hill and Ballard, yet houses about 1.6 million people.
For more subway maps to scale, look here. Although it’s not really fair because some maps (London) include suburban trains while some don’t (Paris). The site’s author must have OCD because he has some strange maps, like this one connecting NYC schools and a map connecting all identically named places. I also want to mention this:

It’s what the US states could look like if they were reorganised to contain equal populations. Although if I were personally responsible for reorganising WA’s borders, I would separate Eastern WA and put Spokane in Idaho where it belongs.
